Summary of the findings The current article evaluated 13 studies, of which eight were randomized clinical trials comparing different administration routes of vitamin B12 in patients with vitamin B12 deficiency
Because it does not measurably raise IGF-1, researchers initially hypothesized it would carry a lower cancer-promotion risk than full-length hGH
The verdict: in most situation, vitamin B12 likely has no effect on hair loss (and hair regrowth), but vitamin B12 might reverse premature hair graying in the presence of B12 deficiency Although hypothetical evidence suggests an absence of B12 activity could negatively impact hair growth, in vivo human studies indicate that either (1) there is no relationship between vitamin B12 deficiency and hair loss and/or (2) there is an overriding factor (like methionine provision outside of the methylation cycle) that prevents B12 deficiency from causing hair loss
Copper accumulation also becomes a theoretical concern at extreme doses, though practical protocols stay well below problematic thresholds
The preservative may lose effectiveness
